About These Birds
Junin Grebe
Junin Grebe (Podiceps taczanowskii) is a medium 30–36 cm flightless grebe endemic to Lake Junin in the Peruvian Andes at 4,080 m. Grey and white; reduced wings; heavy bill. Critically Endangered; fewer than 250 individuals remain. Threatened by water pollution from mining operations, fluctuating lake levels, and gill-net entanglement.
Atitlan Grebe
Atitlan Grebe (Podilymbus gigas) is an extinct large flightless grebe formerly endemic to Lake Atitlán, Guatemala. Similar to Pied-billed Grebe but larger, with heavier bill and flightless wings. Extirpated by the 1980s due to introduced bass predating chicks, reed-bed destruction, and hunting. Last confirmed individuals died in the early 1990s.
